Background: Socioeconomic gaps in children's academic and social skills are large upon Kindergarten entry (von Hippel, Workman, and Downey 2018; Reardon 2011; Reardon and Portilla 2016). Preschool programs may yield particularly large benefits to low-income students and racially minoritized groups and may be promising for reducing inequalities…

Research Findings: The amount of time and type of program that children experience in early childhood settings may be associated with children's kindergarten-entry skills, or kindergarten readiness. Taking a person-centered perspective, in the present study, we examined the extent to which reliable and unique profiles of early childhood…

Do Washington state's targeted, public preschool programs help socially vulnerable students succeed in elementary school? In this study, we explore this question by examining the state's Early Childhood Education and Assistance Program (ECEAP) and the Early Support for Infants and Toddlers (ESIT) program. Using statewide censuses of…

This Education Leadership Portfolio's (ELP) improvement goal was to reduce student chronic absence at West Seaford Elementary School (WSES), a K-2 public school in the Seaford School District (SSD), where I serve as principal. Significant levels of student chronic absence have been and remain common at WSES, and--according to national and state…

A better understanding of factors influencing who receives disability support services through an Individualized Education Program (IEP) or a Section 504 Accommodation Plan from the Rehabilitation Act of 1973 (504 plan) and when is needed. This study used administrative data from11,405 students enrolled in 121 Baltimore City Schools (51% male; 85%…

Structural equation modelling was used to investigate the predictive associations between kindergarten developmental, socio-behavioural, and biotic influences on third grade achievement among a nationally representative sample of low-SES children. The findings validate the understanding that developmental and learning trajectories start early in…

In Maryland, one way children's well-being is measured is by looking at the data from the Kindergarten Readiness Assessment (KRA). While the data can illustrate how children perform on various indicators across language and literacy, mathematics, social foundations, and physical well-being and motor development, it is really a reflection of the…

Math programming that includes assessments to predict standardized mathematics scores can help evaluate student performance and growth during the academic year. ACALETICS® is a highly interactive, culturally inclusive mathematics program that utilizes posttests as continuous comprehensive assessments to evaluate student mathematical knowledge.…

Zearn Math is a popular software platform for K-8 mathematics learning, designed to enable all students to successfully access grade-level content. RAND researchers collaborated with Zearn, the product's developer, to design this evaluation. Then RAND conducted the study independently, randomly assigning 64 schools in an urban Texas district to…

Beginning in the fall of 2017, Maryland severely restricted the use of out-of-school suspensions in grades PK-2. The policy presented a valuable opportunity to examine the effects of state-level discipline policies. This study researched the effects of the suspension ban on student discipline outcomes (e.g., number and frequency of different…

Policy observers have expressed concern over whether misalignment between pre-K and K--12 has negative consequences for children. This study considers students' exposure to redundant content across the pre-K and kindergarten years. Specifically, it asks, to what extent are skills and concepts taught in kindergarten redundant with skills and…

School-age children with overweight or obesity continue to be problematic in the United States, and are associated with many health, social, and financial problems. Schools provide an excellent venue in which to promote healthy weight in students, and school nurses are well-positioned to play an essential role in controlling obesity. The number of…

Background: Over the last twenty years, retention has increased in popularity with policymakers who are concerned with student achievement and aim to end social promotion (i.e., the practice of advancing a student to the next grade level although they have not yet met the academic expectations of their current grade level). Despite calls to expand…

We examined the state of Arkansas, empirically testing how focusing on high-achieving students using state tests might expand the pool of gifted identified students. From a broader sample of 173,133 students, we compared the degree to which students who were academically talented in the top 5% on third-grade state literacy and math assessments…
